November 18, 1995 - Ghost in the Shell
October 1 2002/25 March 2003 - Ghost in the Shell: S.A.C.
January 1 2004/8 January 2005 - Ghost in the Shell: S.A.C. 2nd GIG
March 6, 2004 - Ghost in the Shell 2: Innocence
September 1, 2006 - Ghost in the Shell: S.A.C. Solid State Society

Will it be in my best interest to watch these in this order, so I don't feel lost if, say, (i'll give you an obvious example) i watch S.A.C. 2nd GIG before S.A.C. 1sy GIG?
